So after listening to various exhaust options at FIAT in the Rockies a couple of weeks ago, I really want to upgrade the exhaust on my 2017 124 Abarth.
My main driver is to improve spool up time - I drove a couple of cars with full Roadstersport set-ups including the crosspipe and they did spool noticeably quicker than my car. The added noise was fun too, however I really don't want to go too loud - my better half will have a pretty low tolerance threshold for additional noise.
Firstly, between, a Roadstersport with resonator and crosspipe, and System One with crosspipe and the resonator in place, which is going to be quieter?
Secondly, how much of a difference in noise level do the glass baffles make with the Rodstersport? I know I'd need to drill the Abarth quad tips to fit them.
Third, could the stock Abarth axle back muffler mate up to the Roadstersport midpipe? I'm thinking that might be possible given the Roadstersport axle back mates to the stock midpipe. If that were possible, swapping the stock muffler on might be an option for date nights / road trips with my better half.
